Substituted 4-Benzylfuro[3,2-b]pyrroles

Abstract

Preparation of 4-benzylfuro[3,2-b]pyrroles is described and their reactions with selected dienophiles are discussed. Utilization of 4-acetylfuro[3,2-b]pyrroles for preparation of 4-substituted derivatives of furo[3,2-b]pyrrole and the synthesis of ethyl 4-(2- and 4-nitrobenzyl)furo[3,2-b]pyrrole-5-carboxylates for fusing to a 1,4-diazepine system is presented.
